I like your descriptions of Shasta and Rainier. However, they won't be very helpful unless attached to specific mountain pages.
Before posting more photos, please, make sure they get posted in the right place, so they can be easily found by the users who need beta for a particular mountain or a route. Otherwise they'll get lost among 1000s of pics submitted daily.
If you have any questions regarding posting stuff on SP, feel free to ask on the message board, or contact individual members. Most people here are happy to help.
